FREEBORN F. RAYMOND, 2D, OF NEWTON, MASSACHUSETTS.

HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No.343,339, dated June 8,1886.

Application filed May 6, 1885. Serial No. 164,552. (No model.)

To all whom it may concern.-

Be it known that I, FREEBORN F. RAY- MOND, 2d, of Newton, in the countyof Middlesex' and State of Massachusetts, a citizen of the UnitedStates, have invented a new and useful Improvementin Heel-N ailingMachines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingapart of this specification in explaining its nature.

The invention relates especially to a heelblank-feeding device fortransferring heelblanks from a given position to a position forattachment by the nail-driving devices to the boot or shoe; also to ajack moved automatically into andout of operative position, whereby thejack is moved out of operative position and a heel-blank fed intooperative position for nailing, preferably after the attachment of aheel and before the machine comes to rest upon its last movement, andwhereby the jack is moved rapidly and with out loss of time to aposition from whence the boot or shoe can readily be removed. It furtherrelates to various details of construction.

The invention is represented in the drawings as applied to theheel-nailing machine 7 having many of the features ofthe National.

In the drawings, Figure 1 is a view in front elevation of the centralupper parts of a heelattaching machine containing the features of myinvention. Fig. 2 is a rear elevation thereof. Fig. 3 is a right-sideelevation thereof. Fig. 4 is a section and plan upon and below the line00 a: of Fig. 1. Fig. 5 is a plan view of the mechanism forautomatically moving the jack. Fig. 6 is a view in vertical section uponthe line 3 y of Fig. 1, showing portions beyond said line inv sideelevation. Figs. 7, 8, 9, and 10 are views illustrating the variousdetails of construction, to which reference will hereinafter be made.Fig. 11 is a vertical section of the bed of the machine upon the dottedline 00 x of Fig. 4. Fig. 12 is a horizontal section upon the line y yof Fig. 11, and a plan of the parts in said figure below this line. Fig.13 is a view, part in side elevation and part in vertical section,illustrating the operation of the machine, andtowhi'ch reference willhereinafter be made.v Fig. 14

is. a view in vertical section illustrating the details hereinaftermentioned.

A. is the bed of the machine; A A", the side frames thereof; A, thecross-head, which supports the revolving head A". The revolving head hasan arm, a, supporting a block, a, carrying a gang or group of awls, a",-the arm a, supporting the block a, carrying the group of drivers a; thearm a, carrying the spankerblock a which may have the top-lift holdingdevice a attached. The cross-head is reciprocated, as described in theHenderson Patent No. 259,687, dated June 20, 1882, or by any equivalentmeans, and therevolving head preferably is automatically revolved; and Ihave shown for so doing the mechanism or device described in theHenderson and Raymond application executed March 16, 1885, allowed April18, 1885, although I do not confine myself to this means of revolvingthe head, as I may use the device described in my Patent No. 287 ,472,or in my application filed April 25, 1884, Serial No. 129,212, or anyequivalent therefor.

The mechanism herein described for turning and revolving the head andfor locking it in position, to cause the devices it carries to registerwith the parts hereinafter specified, (shown in Fig. 15,) consists,essentially, of the automatic pawl or latch 13, the guide I), thepassage I), and the automatic switch-block b having point I)" andsurfaces 1) I), and plate b on the revolving head-shaft b which supportsthe cam-pins b. As the operation of this device is fully described invthe application of the said Henderson and Raymond, further descriptionis rendered unnecessary.

G is the templet-plate, and c is the templet. It is reciprocated atgiven intervals in the carriage or table 0 by the lever 0 pivoted at 0and the cam 0* on the cam-shaft O. The table 0 is vertically movable onthe post-c against the pressure of the spring .0

D is the nail-carrier plate, which supports the nail-carrier d.Itisreciprocated at given intervals by the lever d, which is pivoted atd", and the cam cl on the cam-shaft c. The attaching-nails may be placedin the holes of the nail-carrier by hand, or they may be fed thereto byan automatic nail-feeding machine,

. riage or table 0.

such as described in various of my applications for Letters Patent.

E is the jack, which has the flat bearingplate e, arranged to slide insuitable ways in the bed A.

e is the heel support or last. The table 0 has formed in it, beneath thetemplet-plate O, a straight cavity or hole, F, from front to back, whichhas a lateral opening, f, through the side of the table. Thetemplet-plate has the gage-plate G, secured to its front end by bolts y,passing through slots g in the gageplate, whereby it is verticallyadjustable upon the templet. This gage-plate extends below the undersurface of the templet, and acts as an abutment against which the breastof the heel-blank is brought to bear and held, as hereinafter specified.

Fastened to the iemplet-platc, back of the abutment, is the movableheel-holder or clam pplate H. This plate H is moved automatically towardthe gage-plate G by the spring h, and the extent of its movements iscontrolled by the stops it, projecting downward from the templet-plateinto the recess or slots h in the plate H. The front portion or edge, h,of this clamping-plate preferably is V-shaped, and is adapted to closeon the rear or back end of the heel-blank fed thereto, as hereinafterdescribed, and serves to center the same and to press it or hold itclamped against the surface of the gage-plate, as represented in Fig. 8.The pressure of the spring it forces the plate, when released, ashereinafter described, against the back end of the heel-blank, and theinclined surfaces h, in connection with the flat surface of thegage-plate, automatically center or locate the blank.

The heel-blanks are held one above the other in the box K,which issupported by the bracket or post It, extending upward from the bed ofthe machine, and the heel-blank'feeding plate k is arranged upon theupper surface of the post or bracket k, to be moved in the ways k acrossthe lower end of the heel-blank-holding box and into the hole f in theside of the car- This heel-blank feeding or carrier plate isreciprocated by means of the lever k, pivoted at k", and the cam it onthe cam-shaft C. The front edge, It, of the plate preferably is shapedsubstantially as shown in plan in Fig. 12, and has the rounded back por-'tion, k and the outwardly-extending front portion, k". The plate is notas thick as the thinnest heel-blank which it is intended to feed, andthe hole 169 in the box is of a height sufficient to permit the movementof the plate.

The outlet-hole k of the box, or the hole.

through which the heel-blank is moved from the box by theheel-blank-feediug plate,is adjustable in size by means of the plate orgate It, which is movable vertically on the box K by means of the slot kin the plate and the locking-nut It, so as to adjust the size of theopening. This opening of course must be of sufficient size to permit thepassage of but one heel at a time. The heel-blanks are fed from the boxto a vertically yielding or movable plate, M, which is supported beneaththe templet by the carriage or table 0, and has the inclined extensionat into the passage f. It has the pins or studs mflwhich extend from itsunder surface into holes m" in the table, to serve as guides incontrolling its vertical movements, and the spring in, which iscontained in the hole at in the table and bears against the undersurface of the plate, serves to press it upward and holdit in contactwith the stop m". The object of this pressure-plate is twofold-first, toenable heel-blanks of varying sizes to be received in the recess F, and,second, to cause the heel-blank to be held pressed against the undersurface of the templet immediately before and while the clamping andcentering plate H is being moved forward to center the heel-blank andclamp it against the gage'plate. The heel-clamping plate is movedautomatically backward, so as to permit the entrance of the heel-blankto the cavity or recess F, by the block or pin N, carried at the end ofthe rod it, operated by the lever k,whicli rod is arranged to be movedin a hole, a, in the side of the table or carriage c, and as the blockor pin N is arranged in advance of the heel-blank which thecarrier-plate is to move, and so as to be immediatelybrought in contactwith the incline it upon the under surface of the clamping-plate H, sothat upon the inward movement of the heel-blank carrierplate to movetheheelblank into position,the wedge or roll N also is moved forward topush the heel-clamping plate backward sufficient to allow the heel-blankto pass the front end, at, of the clamping-plate; and upon the reversemovement of the heel-blank carrier-plate the wedge-block is of coursewithdrawn and the heel-blank ca rrier-plate is caused by the spring h tobe moved against the back end of the heelblank. t

In order that the heel-blank may not be moved by the heel-blank-carrierplate toofar, I have arranged on the gage-plate the stop 0, whichextends backward therefrom to prevent the heel-blank from being movedlaterally beyond the end of the heel-blank centering and clamping plate.The jack E is movable in and out of operative position by the arm,block,or link 0". which is connected with or pivoted at e to theback end ofthe jack-plate,as shown in Fig. 13, the lever e,which is pivoted to thebed A at c and the arm or link c,which counects the end of the leverwith the cam e upon the cam-shaft C; and this cam is so shaped that thejack is moved from an inoperative position before the awls enter thetemplet to an operative position, and held locked in such position, andupon the completion of the work moved to its inoperative position or toa position to receive the boot or shoe.

\Vhile the jack may be moved automatically both into and out ofoperative position, I prefer, for some reasons,to move it automaticallyonly from operative position upon the completion of the work; and whenthis construction is employed the end of the arm c is not connected withthe jack-plate, but carries the back stop, E, (see Figs. 5 and 6,) whichis made adjustable thereon by means of the pin 6 projecting from the arme'-,which enters the slot 6, and the nut e", which screws upon the pinand clamps the stop to the end of the arm,

and when this construction is used, the time of the cam e is slightlychanged, so that the back stop is caused to move outward at the propertime and then immediately withdrawn, while in the other case the jack ispushed outward and held there until the nextstarting of the machine,when it is automatically drawn back into operative position.

In order that the heel-blank may be auto matically fed into operativeposition,it is necessary that the jack be moved out of operativeposition immediately before the templet is moved into operative positionupon the last upward movement of the cross-head before the machine isstopped. Forinstance, if the spanking of the top-lift is the lastoperation of the machine, then immediately upon the lifting of thespanker-block from the heel the templet is moved forward into operativeposition for the next heel to be attached, and it is desirable that thenext heel-blank to be attached should be moved into position at the sametime, and for this reason I have caused it to be carried by thetemplet-plate; but in order that the heel-blank may be moved intoposition it is necessarythat the work which is completed should be movedout of position to make room for the new blank, and therefore the jackis automatically moved immediately after the top lift has been spankedand while the templet-plate and the heelblank carried thereby are beingmoved into operative position. This movement of the jack of course is ofadvantage in another respect, in that it moves the work to a positionwhere it can be more readily removed by the operator, and does notrequire that he move it, so that a saving in his time is accomplished.

In operation the heel-receiving box is filled with heel-blanks of theproper size. The boot or shoe is placed upon the heel support or last,and is either moved by hand into opera= tive position beneath thetemplet-plate and heel until its back edge shall come in cont-act withthe back stop, or, upon the starting of the machine, it is movedautomatically into place. If it is moved by hand into place before theoperation of the machine, the templetplate maybe moved downward by thelever 1?,to clamp the heel-blank upon the sole of the boot or shoebefore the machine is set in operation. Upon the operation of themachine the awls are moved vertically downward through the holes in thetempletplate, and the awl-block comes in contact with the templetplateand moves it downward, thereby compressing the heel-blank. The awls arewith drawn and the nail-carrier moved into operative position to deliverits nails to the templet. The nail-driving devices are brought intoplace and the nails are driven thereby upon the next reciprocation ofthe cross head. Upon the removal of the drivers from the holes of thenail-carrier plate it and the templet are simultaneously withdrawn, andthis brings the heel-holding devices of the templet opposite theholefinthetable. The heel-blank carrying or transferring plate is thenimmediately operated by the cam W, the clampingplate H being movedbackward and the heelblank being carried by the carrying-plate frombeneath the pile of heel-blanks in the box to a position below thetemplet and between the gage-plateG and the clamping-plate H. The

blank-carrying plate isimmediately retracted, the heel-blanks in the boxfall so that another takes the place of the one which has been fed, andthe clamping-plate H is automatically shut upon the heel-blank, which isat the same time pressed upward by the pressure-plate M, so that it issecured or held to the under surface of the templet in proper positionto be attached. Meanwhile the cross-head has commenced anotherreciprocation for the purpose of spanking on the top lift; and we willsuppose that this is the final operation of the machine upon the heel,although there may be another reciprocation for the purpose of breastingthe heel, when a breasting-knife is carried or supported by therevolving head. ever this may be, upon the beginning of the upwardmovement of the last reciprocation of the machine the jack is movedforward automatically by the cam c and the templetplate, with theheel-blank secured thereto, is moved forward into operative position forthe attachment of the heel-blank to the next boot or shoe. As abovestated the downward movement of the awl-holding block forces the templetdownward and clamps the heel-blank upon the heel-seat of theboot orshoe. Theheel-holding devices are consequently moved down with thetemplet, and after the nails are driven the table is unlatched to permitthe templet to move up- Howward from thejack and to allow the heel-clamping devices to clear the top of the attached heel. In some instances itwill be desirable to automatically release the heel-blank-clampingplatewhile the heel is held compressed and before the templet has lifted, andthis is accomplished by the dog S, which is pivoted at s in averticalslot or hole, 8, in the templetplate, so that its lower end, 8 comes inline with the pin 8, projecting outward from the edge of the clamp-plateH,which will move it upon its outward movement to clamp a heelblank andelevate its upper end, 8, above the top of the templet-plate into aposition to be thrown down or back by the projection s of thenail-carrier plate as it is moved forward, and this backward movement ofthe dog moves the clamping-plate backward sufficiently to clear it fromthe heel-blank, and it is held in this position while the nails arebeing driven and the templet lifted and until the nail-can rier plate iswithdrawn.

X'Vhile for the purposes of this construction of machine I have shownthe templet as a heelblank carrier, I do not intend to limit theinvention thereto, as any movable or reciprocating plate bearing theheel-blank-holding devices may be used in lieu thereof; neither do Iconfine myself to the specific devices herein shown and described, foreffecting the automatic feeding of the blank, but may use any mechanicalequivalent therefor. It will beseen that the heel-blank is moved fromthe stack of heels by one movement to a position under the templet. Itwill be seen that power is communicatcd by the pullcy-shaft R and by thepinions It to the gears It on the crank-shaft R and to the pulley-shaftO by the pinion R, (see Fig. 2,) gear It upon the intermediate shaft,R", pinion R thereon, and the gear It on the shaft 3.

The mechanism for starting and stopping the machine is like thatdescribed in my pending application filed April 25, 1885, Serial N 0.163,440, as is also the mechanism for locking the table 0 in its lowestposition and for automatically unlocking it. It is of course necessarythat the heel-blank, after it has been attached, and its feeding-platehave a relative vertical movement from each other, in order that thegageplate (l may clear the top of the heel-blank as the jack is movedoutward; also that the same conditionsprevail when the heel isbliiu'l-nailed.

I would not be understood as confining myself to the special form ofblank holding or clamping device herein specified; but I may use anyequivalent mechanism for holding the blank to its carrying-plate and forcentering it thereon.

The gageplate G, I have shown in Fig. 14 as provided with a horizontaladjustment upon the end of the templet-plate, and when so adjustable, Iprefer to shape it as represented in said iigure, and adjust ithorizontally by means of a screw having a collar, g". \Vhen the jack isautomatically moved in both directions, I prefer to make the connectionbetween the reciprocating arm, bar, or block operating it and thejack-plate substantially in the same way as that between the back stop Eand its operating block, bar, or plate; or, in other words, so as toprovide for a horizontal adj ustment of the jack in relation to saidoperating arm, bar, or plate.

It will be noticed that the entire operation of supplying the heel-blankto the heel-nailing machine is automatic, and the blanks are not onlyautomatically fed to position for attachment, but that they areautomatically located and clamped before said feeding and automaticallycentered; also, that the clamping mechanism is automatically releasedbefore the blank carrier and plate is moved from the attached heel orthe heel from it. It will also be noticed that in a machine in which thetemplet-plate is not moved horizontally the devices for feeding theheel-blanks automatieally thereto herein described can be used exactlyas herein specified.

Having thus fully described my invention, I claim and desire to secureby Letters latent of the United States- 7 1.
